Application filed Gctober 28, 1914.

To @ZZ whom t may concern.'

Be it known that I, J osnrn BARTL, a citi- Zen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Fastening Devices or Sash-Locks; and I do hereby declare that the following is a full, clear, and

Vexact description thereof, reference being had to the accompanying drawings,.and to the letters of reference marked thereon, which form a part of this speciiication.

This invention relates to adjustable fastening devicesor sash locks.

It relates particularly to fastening devices or sash locks for fastening inner and outer or upper and lower sashes of windows together in different adjusted positions.

The principal object of the invention is to provide a simple, economical, and eilicient fastening mechanism, adapted to secui-ely fasten or lock a sash or similar device in partially opened or in closed position, as desired. V

A further object is to provide a fastening device adapted to secure the inner and outer or upper and lower sashes of a window together, with the window closed, and to enable the sashes to be fastened or locked together on the inside, with the upper sash lowered or with either or bothsashes partially opened or moved from closed position, in such a manner that the releasing of the fastening means, and the disconnecting of the sashes from the outside while the window'is open or partially open, will be prevented.

Other and further objects of the'invention will appear froman examination of the following description and from an inspection of the drawings which are made a part hereof.

The invention consists in the features, combinations, and details of construction herein described and claimed.

In the accompanying drawings, Figure l is a view in elevation of a window/fastening device or lixture, constructed in accordance with my invention and improvements, and showing the same in operative position upon the sashes of a window, the fastening device being shown with the parts in position for fasteningV closed sashes together in full lines. and with Vthe hooked arm or guard in raised position in broken lines; Fig. 2, a

In constructing a fastening device, locking guard. or sash-lock in accordance with my invention and improvements, I provide a locking or pivoted catch member or latch 12 adapted to be mounted on a movable member to be locked, such as an inner or lower sash a, and a pivoted hook member or guard t which is adapted to be mounted on an outer or upper sash b. The sashes a and b shown in the drawings are usually mounted in a window frame comprising side frame members c, a top frame member (Z, a bottom frame member e, and window stops f and f', all of which may be ofany desired, ordinary or well known form. The bottom or inner sash shown in the drawings comprises the usual side members g, bottom member 7L, and top sash member z', slidably mounted between the window stops f in the ordinary manner, and the upper or outer sash comprises side members v, a top member Z, and a bottom member m forming a supporting frame for a window pane n, said sash being also slidably mounted between inner and outer window stops f in the ordinary A latch or locking and releasing catch is mounted on the inner or lower sash and comprises in its construction a metallic base and loop or socket-forming member o, which l is mounted upon and securely attached to or anchored in the upper or horizontal sash member m of the lower or inner sash, by means or screws or rivets 79 or other suitable securing means. (See Figs. 2, 3, 8 and 9.) This base member is provided with an in` tegral loop portion g on the side adjacent to the upper or outer sash, forming a socket having a recess or vertical slot r adapted to admit the depending upright hook portion s of a hooked arm or guard member t, which is mounted on the adjacent outer or upper sash. Said arm or guard member is pivotally secured to the outer or upper sash by means of a supporting bracket u having a base portion o provided with apertures 'w adapted to admit securing screws or rivets or other suitable securing means for anchor- 'ing or rigidly securing said supporting bracket to the bottom member m of the outer cr upper sash and on the inside of the window pane ot' said sash. This supporting bracket or member u. is provided with a vertical or upwardly and laterally opening recess or slot y, into whichY the lower or pivoted end of the hooked arm or guard member t extends, (see Figs. '2, 3, 6 and 7), and said pivoted hooked arm or guard member is provided with an elongated aperture 9. therethrough, through which extends a horizontal pivot 3, one end 4 of which is rigidly secured in a suitable perforation in the bracket member u, pret'- erably by being riveted to said bracket member, and the other end of which is provided with a heat 5 or similar suitable arm-en gaging means adapted to securely hold the arm t upon the pivot or or pin 3. The bracket member u has securing shoulder portions 6, (3,' which are adapted to engage the arm or guard member z5 when the latter is in upright or raised position between said shoulder portions (see Figs. 2 and 3), and a spring 7 is mounted upon, and by preference inside of the bracket member u and in posi-- tion to project at an incline into the slot ,1/ of said bracket member u. This spring is securely held in operative position by means of a shoulder portion 8 of the pivot pin or rivet 8, the upper portion 9 of said spring being in yielding engagement with an outwardly facing part of the pivoted arm or guard member t. (See Figs. 2 and 3.) The spring is thus adapted to yieldingly press said guard or hooked arm inwardly into the recessed portion 10 and between and removably in engagement with the shoulders 6 of the bracket member u, in which recessed portion said arm or guard is yieldingly held in upright position. The hooked arm or guard memberft, thus held in upright position, cannot be lowered or turned downward or to horizontal position except by first pressing said guard member outward out of engagement with the shoulders 6 and then turning the same downward.

The bracket member u, which vforms a support for the hooked arm or guard member t, is provided with a rigid securing hook or latch-engaging shoulder portion ll in the upper portion o1" saidbracket member, which projects inward or toward the inner' or adjacent sash. Said fixed shoulder or hooked portion l1 is above the level of the loop portion (j of the member 0 on the inner or lower sash when the sashes are in normal or closed position and in position to project over and in securing or locking engagement with a. pivoted latch member or catch l2 on the inner or lower sash. The latch member or catch 12 is pivotally mounted upon the base member o to which it is secured by means of a. suitable vertical pivot 14, said pivot being secured to the base member o by means of a nut or riveted end portion 15, or other suitable seeuring means. The latch or securing member 12 has an operating lever or handle portion 13,y and is provided with a circular with the upper sashpartially lowered with or segmental, peripheral rim portion 16 which extends upward and in theA direction curved and inclined edge or rim portion is thus adapted to extend into interlocking engagement with the slotted or recessed under side portion 17 of the fixed hook 11, already described. A boss or depending sleeve portion 18 on the latch or sash-lock member 12 extends into a suitable recess 19 in the part o and, with-the vertical pivot pin 14, serves to securely hold the latch or sash-lock member 12 in position to enable the latter to be readily turned in a horizontal plane into and out of locking engagement with the fixed hooked portion 11 of the bracket member u, and into and out of lookin g engagement with the pivoted hooked arm or guard member t when the latter is in upright or operative position respect to the lower sash, or with the sashes or either of them in partly opened position. (See Figs. 2, 4 and 5.)

rllhe loop portion g is provided with an upwardlyopening notch or recess g having side shoulder portions s which engage the horizontal or bow portion e when the hooked arm or guard member t is in locked position between the loop q or base 0 and the pivoted locking member 12. (See Figs, 5, 8 and 9.) ,`he outwardly or rearwardly facing opening or slot Q may be as much narrower than the oval or elliptical slot or socket portion 'i' as desired and may be of any desired length vertically so as to bisect the loop y to any desired extent, and the sash member z' has a recess 20 directly beneath the slot or opening 1 in the inclined outer side face of said sash member, said recess being tapered in the direction ot its lower extremity so as to leave the outer bottom edge of the sash member i unbroken and straight or whole, and

permit the verticalhook portion s to extend Athe spring 72L is shown mounted on the pivoted arm member t and in yielding engage` ment with the bracket member u. The arm s of the Vhook member being of such length that when it is in raised or upright position Aits lower end will extend down to a point so near to the top ot the slot r and loop g, when the sashes arein closed position. that the first movement of the upper sash downward with respect to the lower sash or of. `the lower sash upward with respect to the upper or outer sash will cause the lower end of the hooked arm portion s to at once extend into the socket r or loop g and lock the sashes together in such a manner as to fpermit them to be moved to partiallyopenedposition, but positively limit the extent to which they can be opened, and prevent the removal of the hooked arm portion s from locking engagement with the loop g excepting only when the sashes are in closed position.

1n operation, the sashes may be locked in closed position, as shown in Figs. 1 and 2, by turning the pivoted latch or locking member 1Q, into position to extend into locking engagement with the fixed hook portion 11 of the bracket member u, so that the curved rim or flange portion 1G is in the notch or recess 17, as shown in said Figs. 1 and The hooked arm member or guard z5 is adapted to be placed in normal or horizontal position, as shown in full lines in Fig. 1, so as to permit the sashes to be opened upon turning the pivoted catch or locking member 12 to releasing position or out of engagement with the part 11 of the bracket member u. The locking member 12 is shown in locking position in full lines in Fig. 3, and in releasing position in broken lines in the same iigure. The hooked arm t may be moved to and allowed to remain in raised upright position, as shown in broken lines in Fig. 1, with the catch 12 either in locking or releasing position as desired. By having the pivoted catch or locking member 12 turned to releasing position with the hooked arm or guard t' in upright position, it will be readily seen that the lower sash may be raised or the upper sash lowered to such relative positions that the hook or arm s is in position to extend through the loop q, with the upper extremity or bow portion s of the hook member in engage -ment `with the loop (j and in position to be locked in engagement with said loop by turning the pivoted catch or sash lock member 12 into locking position, or into position to extend over and in locking engagement with said upper extremity or bow portion of the hook member or guard i. (See Figs. 5 and 10.) The sashes are thus securely locked in fixed relation, and in position to permit the top sash to be partly open at the top or the bottom sash partly open at the bottom or both sashes in position to leave an opening at top and bottom, for the purposes of ventilation, etc., but with both sashes securely locked together in such a manner that neither sash can be opened to any greater extent than that permitted by the hooked arm member t and the locking members comprising the base or socket member o with its loop q and socket or opening r, the pivoted latch or sash lock member 12, and the bracket u with which the hooked arm or guard member t is pivotallv connected. T he releasingor unlocking of the sash fastening or locking mechanism from the outside is i thus prevented, not only when the sashes aieleseapeatiee, Waalse altari-@listage or both sashes are in partially open position, and the extent to which the sashes orl either of them can be opened is positively limited, and the saslies are securely locked together with either or both sashes in partially open position. The top sash may be lowered from the inside with facility by rst raising the lower sash and locking` the sashes together and pulling down upon the lower sash, thus bringing both sashes down to the position shown in Fig. 10. The rattling oi the sashes is prevented not only when they are closed but when they are connected together in partially opened position as described.

A shoulder portion s is provided upon the lower extremity of the arm a of the hooked arm member t, and the bottom end portion 2l of the arm s is offset with respect to or of smaller cross-sectional area than the shoulder portion, so that the part 21 is adapted to extend through the opening 17 in the pivoted catch or sash lock member l2, When the latter is in locking position, as shown in Fig. t. The -further movement of the part s with respect to the catch l2 and loop Q is thus prevented by the shoulder or bottom extremity of the hook portion s. The mechanism is thus adapted to be locked in the position shown in Fig. a, in which position the sashes are securely locked in a different partially open position from that in which they are shown in Figs. 5 and 10. lVith the parts in the position shown in Fig. 4:, the locking member or pivoted catch 12 is prevented from being turned to releasing position until the outer sash is raised or both sashes are closed. so as to bring the bottom end of the part 2l or hooked arm portion s out of engagement with the opening 17 in the pivoted sash locking member' 12. The pivoted lockingmember 12 can then be turned to releasing position. and from releasing position back to locking position or to position to permit the part 2l to pass through the opening 17 with the sashes in the partially opened position in which they are shown in Fig. 4.
